After producing electricity generation for more than 40 years, Fessenheim-2 was disconnected from the grid on June 29, some four months after the retirement of its companion reactor, Fessenheim-1 (NN, Mar. 2020, p. 83). The action completes the closure of what had been France’s oldest operating nuclear power facility.

Both Fessenheim units are 880-MWe pressurized water reactors; Unit 1 began commercial operation in December 1977, with Unit 2 going on line in March 1978.
